Application led December 3, 1913. Serial No. 804,353.

transmitting power from a suitable -source machine `or maw` of energy to the desired chines.

The device herein described yis barticu-l larly adapted and designed to be used in connection with my portable power ytransmission device described in my pending application filed October 2, 1912, Serial No. 723,534, for use on farms for drivingdifferent kinds of machinery, as for example, churns, washing machines, pumps, grindstones, shellers, or similar tools and appliances, and the various other machines that are commonly used upon farms.y With it onefor more pieces of apparatus may be driven from a single shaft without the use of countershaft and intermediate belting, and the like. y

The invention has among its objects the production of an attachment or device of the kind described that `is simple, convenient, eiiicient, and satisfactory; that `may be manufactured at comparatively small cost, and used wherever found applicable.

To this end my invention consists in the.`

novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like yreference characters indicate like or corresponding4 parts, Figure 1 is a side elevation of my device, provided with one form of `base or support; Fig. 2 is substantially a sectional view taken on line 2, 2 of Fig. 1; Fig. 3

is substantially a sectional view taken on line 3, 8 of Fig. 1; Fig. 4e is a view similar to Fig. 1 with the device given a quarter ofm a turn to showanother side; Fig. 5is substantially a sectional view taken online 5, 5 of Fig. 4f. i

Referring to the drawings, in which `my preferred form of device is shown, 1 and 2 represent two shafts, one of which, as shown shaft 2, is adjustable about the other ktain the two in close contact.

through an angle of 3600, or less, as may be desired. As shown, the shaft 1 is supported in a suitable part 3, which, in the construction shown in Fig. 2, is carried by a support 4, which may be placed upon a box, block, or the ground, or wherever desired. It may be fastened down, or not, as may be found expedient. The shaft 1 is provided with a gear 5, secured thereto, and also carries an adjustable bearing G, which, in the preferred construction, is arranged between the gear 5 and extended end 31 of the bearings 3. The adjustable bearing 6 and shaft 1 carry the endof the shaft 2, which shaft is provided with a gear 7, secured thereto andarranged to mesh with the gear 5. A collar orA additional bearing 8 is also provided on the shaft 2, the same being connected to the collar or bearing 6 by the brackets or" parts 9. These parts are shown on both sides, but may be formed upon one side only, if desired, the combination shown being somewhat stronger. 11s is obvious, with these adjustable bearings, the shaft 2 may beadjusted about the shaft 1 as desired.

Any desired means may be provided for maintaining 'the bearings and shaft in the desired positions,relative to the bearing 3 and shaft-1. As shown, a part 12 is rotatably arranged on the end 31 of bearing 3, and provided with an extension 10, which is preferably secured by bolts 11, or their equivalents, to the collar 2. l Secured to bearing 3, as shown, formed integral therewith, is a plate 15, provided with the desired number of holes 17 therein, or their equivalents. 12, is preferably provided with fingers 14 extending over the plate 15, so as to main- Part 12 carries a pin 16, arranged to engage in the holes 17 in plate 15, so as to lock the parts in the desired positions relative each other. The construction is most clearly shown in Fig. 5. Referring to this ligure, the pin 16 is carried by a bracket 1S, and is normally maintained in engagement with plate 15' by a spring or its equivalent 20, arranged between the collar 19 and the part 18. Carried by the part 12 is a suitable lever 21,

.having an end 23 arranged to engage with the collar 19, the lever 21 being pivoted vat 22 to the brackets 24:. Pushing or moving the free end of the lever 21 toward plate 12, withdraws the pin from' engagement with the plate 15. The pin may be posi- One part, as shown the platetionedin any desired hole so as to lock part 12 against movement, and consequently retain the shaft 2 in the desired adjustment, which adjustment, of course, is determined by where the power is to be transmitted to or received from, as the case may be. might be mentioned that any suitable equivalent for the pin 16, and holes in the plate l5, may be employed. The construction herein described, however, is adjustable without requiring tools, and in an instant.

As was previously mentioned, the device is particularly intended and desirable for use in connection with my portable power transmission mechanism, but its use is not confined to that. Powermay be transmitted to receive it from either end of the shaft v1, or transmitted to or received from the end of shaft 2. Likewise, with triiiing modiications, it might be arranged for more than the number of shafts shown inthe drawings.

`Having thus described my invention, any immaterial modifications may be made in the same without departing from the spirit of my invention; hence l donot wish to be understood as limiting myself to theexac't form, construction, arrangement or combination of parts herein shown and described, or usesmentioned. t

l/Vhat I claim as new and desire to secure y by Letters Patent is l. In a device of the kind described and in combination, a shaft, a bearing therefor, a second shaft,an adjustable bearing therefor carried by said first mentioned shaft, and adjustable means for positively locking said second bearing in the desired position. comprising aplaterotatively mounted on said first bearing, and operatively connected with said adjustable bearing, said first mentioned bearing provided ywith a flange having al plurality of perforations therethrough, means for maintaining said plate in close relation'with said flange, a pin carried by said plate rand movable into engagement with said flange, means for yieldinglymaintaining` said pin in engagement with said flange, and means for moving the pin lengthwise out of engagement with the flange as desired.

2. In a device of the kind described and-in combination, a rotatable shaft, a bearing for carrying said shaft,ra suitable support for said bearing, a gear securedlon said shaft, a second bearing larranged on said shaft and carried thereby betweensaid gear and said rst mentioned. bearing,a second shaft having its end rotatably carried by said second bearing, a collar bearing arranged onsaid second shaft and operatively connected with said: second bearing, a gear secured to said second shaft between the second mentioned bearing and said collar bearing, and arrangedto ymesh with said first' mentionedgear, and means for adjustably securing said collar bearing to the rst mentioned bearing, comprising afplate rotatably arranged on said first mentioned bearing, said plate connected with said collar bearing, and means carried by said plate for engaging a portion-of said first inentioned bearing. l Y

In testimony whereof, I have `hereunto signed my name in the presence `of =two subscribing witnesses. Y
